A fire prevention test device for lubricating oil pump with external circulation of oil and gas

Abstract

The invention discloses a fire prevention test device for a lubricating oil pump with an external circulation of oil and gas. The lubricating oil pump and the burner are arranged in the combustion chamber. The exhaust device is connected to the combustion chamber and is used for exhausting the combustion chamber. When the oil pump works, the heating oil tank supplies oil to the oil supply level of the lubricating oil pump through the pipeline, and the oil supply level outlet and the oil return level outlet of the lubricating oil pump pump the lubricating oil back to the heating oil tank; the heating oil tank is also connected to another pipeline, which passes through the variable The oil pump pumps the lubricating oil from the heating oil tank to the oil-air mixing device. The oil-air mixing device mixes the lubricating oil and air to generate an oil-air mixture. The oil return stage of the lubricating oil pump is connected to the oil-air mixing device and pumps the oil-air mixture back to the heating oil tank. Carrying out the fire protection test through this equipment can not only realize the operation of the lubricating oil pump, but also simulate the actual working conditions of the lubricating oil pump installed on the engine to extract the oil-gas mixture, and can more simply and accurately guarantee the lubricating oil supplied to the oil-gas mixing device. oil volume.

Description

technical field [0001] The invention belongs to the technical field of mechanical structures, and relates to a fireproof test device, in particular to a fireproof test device for a lubricating oil pump with external circulation of oil and gas. Background technique [0002] The lubricating oil pump is the core component of the mechanical lubrication system. Its function is to continuously circulate the lubricating oil in the lubrication system to achieve lubrication and cooling of gears, bearings and other parts in the mechanical transmission system. [0003] The existing fire prevention test equipment for lubricating oil pumps can realize the fire prevention test while the oil supply level and the oil return level respectively extract lubricating oil from the oil tank under the running state of the lubricating oil pump. At this time, the oil return stage of the lubricating oil pump draws lubricating oil from the fuel tank, which is inconsistent with the working state of the ...

AI Technical Summary

Problems solved by technology

The self-circulating oil-air mixing function fire prevention test equipment provides lubricating oil to the oil-air mixing device through the oil supply stage of the lubricating oil pump, and the amount of lubricating oil is guaranteed by the spray hole area of ​​the nozzle installed in the oil-air mixing device and the outlet pressure of the oil supply stage. , while the outlet pressure of the oil supply stage of the lubricating oil pump is a specified parameter in the test. In order to adjust the amount of lubricating oil, it is necessary to constantly explore and adjust the nozzle hole area. The adjustment process is complicated and it is not easy to adjust accurately
